NATHANIEL E. BAKER, OF HOLYOKE, MASSACHUSETTS.

SASH-SUPPORTER.

Specification of Letters Patent No. 18,376, dated October 13, 1857.

To all fro/tom may concern.'

Be it known that I, NATHANIEL E. BAKER, of Holyoke, in the county ofHampden and State of Massachusetts, have invented a new and ImprovedDevice to be Applied to iindow-Sashes for the purpose of Retaining Themat Any Desired Point or Height; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings,`making a part of this specification,in Which- Figure 1, is a side or face view of a sash iitted in its frameand having my improvement applied to it. Fig. 2, is an end view of thewindow frame. Fig. 3, is a horizontal section of the sash frame and myimprovement taken in the line Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to an improvement in that class of window sashholders in which friction is employed as a means for retaining the sash.

The object of the invention is to obviate the difficulties hithertoattending such devices, viZ: the abrasion of either the sash or windowframe by undue friction and the slipping down of the sash owing to aninsutiiciency thereof caused by wear or otherwise.

The invention consists in having a clamp attached to one side of thesash, which clamp is made to sustain or hold the sash by grasping a cordwhich is placed within one of the jamb posts or stiles of the windowframe as hereinafter described.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents a window frame and B represents a vertical sliding sashfitted therein.

These parts are of usual construction and therefore do not require aminute description. To one side of the sash B there is attached a metalplate C. This plate projects outward from the sash a suitable distanceand its outer edge is curved, as shown at (a). A similar plate D, isplaced against the plate C and is secured thereto-by an india rubberband (b) which passes through openings (c) in said plates. The outer endof the plate D is rounded as shown at (d) and the inner end has a shank(f) attached, said shank being lit-ted in or passing through a recess ormortise (e) in one of the Stiles of the sash, said shank being ofsuitable length so that it may be readily acted upon by the thumb orfinger.

E represents vertical cord which is fitted in a recess (f1) cut in thejamb post shown clearly in Figs. 1 and 2. This cord is not drawn orstretched taut in the recess but is allowed to be somewhat slack. Thiscord is grasped by the plates C, D7 which consequently retain or hold upthe sash at anydesired point. The sash being allowed to move freely atany time by pressing upon the shank which will throw out the rounded orcurved end of the plate D from the cord E. It is not absolutelynecessary that the shank be attached to the plate D for the sash may bemoved by applying the hand to the sash without throwing the plate D outfrom the cord, but it is preferable to relieve the cord from thepressure of the plates when the sash is moved as it prevents the wearingof the cord. y

By having the cord E fitted rather slack in the recess its bers will notbe distended and it will consequently be more pliant so that the plateswill be .less liable to slip upon it than otherwise and the cord willalso be subjected to less wear. It will be seen that by this improvementneither the sash nor the window framing are injured by friction as isthe case with most of the friction devices employed for the purpose norare the sustaining parts liable to become worn so as to be rendereduseless. I do not confine myself to any precise form of spring to beapplied to the plates C, D, nor to any precise material for the cord E.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is,

The clamp formed of the plates C, D, attached to the sash B, incombination with the cord E arranged substantially as andv 'for thepurpose set forth.
